25. Ação inibitória de extratos de plantas do Cerrado sobre α-amilases com ênfase em Kielmeyera coriacea
α-amylases are digestive enzymes widely distributed in microrganims, plants and animals, that catalyze hidrolysis of α-1,4 glicosidic bonds and act in carbohydrate metabolism. The inhibition of α-amylases can be applied on control of insect pests that depends on starch-rich diet to energy production, reducing the amount of nutrients to avoid i
